Further Information: Heritage Inventory sheets are often not comprehensive, and should be regarded as a general guide only. Inventory sheets are based on information available, and often do not include the social history of sites and buildings. Inventory sheets are constantly updated by the City as further information becomes available. An inventory sheet with little information may simply indicate that there has been no building work done to the item recently: it does not mean that items are not significant. Further research is always recommended as part of preparation of development proposals for heritage items, and is necessary in preparation of Heritage Impact Assessments and Conservation Management Plans, so that the significance of heritage items can be fully assessed prior to submitting development applications.

Historical Notes: The “Eora people” was the name given to the coastal Aborigines around Sydney. Central Sydney is therefore often referred to as “Eora Country”. Within the City of Sydney local government area, the traditional owners are the Cadigal and Wangal bands of the Eora. .

With the invasion of the Sydney region, the Cadigal and Wangal people were decimated but there are descendants still living in Sydney today.
